A Disneyland employee took to social media after a pin-festooned lanyard, which apparently belongs to a person with autism, was found last week in Anaheim — and now a Facebook post announcing the search has gone viral.

The red lanyard was discovered the morning of March 24 by a “cast member” at the Disneyland Hotel, according to a spokesperson for the Disneyland Resort.

Four pins had been attached to the lanyard, along with a note that stated: “Hello! I am autistic, and I don’t talk much, but I would like to trade for Mickey pins!”

The hotel worker took the item to Emily Gibby, a colleague who was working at a pin-trading event held at a kiosk in the Downtown Disney District, the spokesperson said.

“So we did what any cast member would naturally do,” Gibby later wrote on Facebook. “We filled up his lanyard with Mickey pins and got him a Mickey medallion as well!”

The medallion depicts a smiling Mickey Mouse, framed by the words “PIN TRADING” and “Disney Parks.”

“But now we need everyone’s help in finding him/her!!” Gibby’s post continued. “Share this post and help us find our friend!”

As of Saturday evening, the appeal has been shared more than 12,000 times on Facebook. A similar post on Instagram has received almost 300 “likes.”

The owner of the lanyard, or anyone who could help return it to that person, was encouraged to call the Disneyland Resort at 714-781-7277, or send a message to Gibby on Facebook or Instagram.

We filled up his lanyard with Mickey pins and got him a Mickey medallion as well! But now we need everyone's help in finding him/her!! Share this post and help us find our friend! ! Let's work some magic and try to find our friend!! So far we have learned that there were a few kids that had similar lanyards on (allegedly we are thinking the boys and girls club).
